Motivation.

It took Naruto less than 7 days to completely master Senjutsu when he himself had been learning about it. Even when you considered the fact that he was using a couple of clones to speed up the learning progress by only double. With the right motivation, something that took his master 50 years to learn (not master, just learn it) had taken him a few days to learn how to do it.

Koneko didn't have the motivation to learn Senjutsu.

'Refusing a vital part of herself... of course with the knowledge she can learn Senjutsu in a safe way, even she would decide to try and learn it.' Naruto thought to himself mostly. He glanced at Koneko as she walked next to him, slightly behind him. Her body was more petite than even Fujimai's body was, her frame generally smaller than her mother or her sister. Kuroka was a petite woman in frame, even if she had wide hips and large breasts. "It seems that Nekoshou in general are rather petite, huh?" Naruto asked Koneko as they walked.

She looked at him with some confusion.

"Huh?"

"Nekoshou are naturals at Senjutsu, able to use it with almost no training. It takes a lot of chakra to use Senjutsu, and usually a person with a lot of chakra has a bigger build to them. Nekoshou are born with surprisingly good reserves for a petite race is all." Naruto explained his comments to the girl. He needed to break the ice, since her training was going to be more awkward for her than either her mother or her sister's training was.

Her training was going to be hell on her, mentally, physically, and no doubt also emotionally.

"I guess?" Koneko looked down at her chest when she said that. "My sister was buxom, so-"

"You can be petite and have a large chest, my late wife was the same way. She was very buxom, but she had a very petite frame. She was a very good woman, wife, and mother. I'm just making some light talk with you before I put you through hell." Naruto informed her. They had a bit of a walk before they would arrive at the forest that she would be getting her training. He needed access to a body of water at minimum the size of a lake, and above that, he needed access to trees and leaves.

Koneko was silent, and a little more than submissive as she kept her head down. Something had been bothering her for a week before Naruto had even arrived, according to Azazel.

"... How did you know where I was?"

"I didn't, I expected you to come to my island one day. You see, I asked Ophis if she knew anyone who could set up an Internet Connection on my island for me. She's the one who introduced me to Azazel, and he told me you needed my help. I spend so much time on the island, that I need a break from it." Naruto explained simply. He didn't know where she had been, and he never made any plans on going to see her. "You look a lot like her you know, it's like looking at a mini-Fujimai. She became a very beautiful woman, Kuroka didn't look very much like her, except for her eyes of course." Naruto chuckled a little to himself, and he looked up and down Koneko.

He sighed.

"Was Mother... very... big?" Koneko gestured to her own breasts.

"Not really, she was about average. Still, don't worry too much about breast size."

"Guys prefer big chests."

"Any man who expects you to have a large chest size to please him, isn't something you should be with. Teenage boys, yes, are very shallow and do go after those types of women. Any guy that refuses to date you because of something silly like boobs isn't worth your time." Naruto comforted her on an issue she seemed to be more than slightly self-conscious about. They entered the forest at this time, but it would still be a little bit of a walk before they would get to the lake.

Flying or running would be so much quicker than this, but that wasn't the point of taking the walk in the first place.

"What was she like?" Koneko asked.

Her question was obvious.

"A complete failure, but still my favorite student. No matter how many times she failed, she got back up and tried again until she succeeded. At your current levels of fighting ability, you're on par with her." Naruto admitted that Fujimai had never gained that much fighting power when compared to other students. She had never recieved much of his combat training that Kuroka had gained, nor did she seek that training.

Her training had been on mastering her chakra, and becoming great at senjutsu through mastering her chakra.

"So... she was that weak?"

"Yes, she wasn't that strong. That being said, you don't even have half of the chakra reserves that she gained through years of training. In that aspect, you've yet to come close to her." Naruto wouldn't say that Fujimai was anything other than a dazzling star among his students. It took her so much longer to learn anything, and a lot of trial and error, but she always got stronger for her mistakes. "Are you weak Koneko?"

"No... yes... everyone else is getting stronger way faster than me." Koneko didn't have a choice but to admit this.

This was her mother and sister's master, and for the next 20 days, he was going to be her master as well. Rias had signed off on him training her, which meant that she needed to be open with him and consider his word to be on par with Rias' own word.

Naruto frowned thoughtfully.

"Well, I guess your starting level was higher than their level was."

"Huh?" Koneko asked him.

"Sorry, I just remembered my son complaining about how slowly some video game characters leveled up. It takes longer for people to level up at higher levels... you started off stronger than them, but they quickly gained strength until they not only caught you, but surpassed you... and it scares you right?" Naruto asked her, since this was something he had experience with as well. The feeling of inferiority compared to others, and the drive to be better than them.

Koneko was conflicted.

She was happy the others were getting stronger, but comparing the progress her friends had made to her own progress showed off how little she was gaining strength. Now that her friends had surpassed her battle power, she was feeling useless and weak. There was slight resentment towards her friends, guilt that she was feeling that resentment, and a burning desire to get stronger as fast as possible.

She knew that she could get stronger if she used Senjutsu, but she was scared of her own bloodline born gifts.

"You've got children?" Koneko didn't see this young, but older, man as having children. Of course, he was clearly old enough to be her mother's master, so his looks were no doubt deceptive. He smelled human, so his youthful appearance didn't make much sense either.

Naruto raised his hand.

"I've got 5, my first born son Boruto, my second born child Himawari. While it was never official, I did adopt a child into my house and became like a father to him. Then recently I had 2 more children with my current girlfriend... lover... partner... our relationship is complicated." Naruto didn't know what to call himself and Ophis. Naruto glanced at Koneko, who was being more attentive to his story now.

That was a talent of his.

He was very good at breaking through people's barriers, and getting to know them. People always told him that he was easy to talk to, and even without knowing him long, gained high levels of trust in him.

Well, he had been a kind and loving leader of his people, and he always did have high charisma.

"Will I really get stronger under you?"

"If you don't give up, then I promise you will become stronger under me. You have got more potential than your mother and sister combined. To be honest, if you had trained with that power inside of you for even 1 year, you could become stronger than your sister is right now." Naruto saw that much potential for growth and improvement inside of the girl. Koneko's eyes widened in surprise when she heard the words, and she looked at Naruto's back.

She saw a red spiral on it.

Koneko remembered seeing that spiral.

"... That was my mother's symbol...I think."

"Hm?" Naruto was a little confused, before he looked at her staring at the back of his jacket. "This is the Uzumaki clan symbol. When a student proves themselves worthy, I allow them to wear this symbol. It's a sign that I am their Master, and that they are an honorary member of the Uzumaki clan." Naruto informed her as he gestured to his own back with his thumb.

There were only 4 living Uzumaki who had actual Uzumaki blood, but to say the Uzumaki clan was larger than that wasn't a lie either.

"Does my sister... wear that symbol?" Koneko shifted her gaze away from the symbol.

Her mother had been an honorary member of this Uzumaki clan.

"Yes, Kuroka wears this symbol as well. Kuroka was the foremost genius of any student I had ever had. She came to my island an arrogant little shit, and left it a mature young woman. Naturally, she's been calling herself Kuroka Uzumaki." Naruto didn't have a problem with her taking his last name for herself. He wished that she had asked, but the thing about her having his symbol on her clothes, was proof that she had trained under him and completed enough of his training to be called a worthy student.

"She's a murderer."

"You would be too if you needed to kill to protect somebody you loved." Naruto knew that Koneko had said that without meaning too. He still took it seriously though, and responded in kind with the truth of the matter.

His words flew over Koneko's head, since she had been too absorbed in her own thoughts to really register that he was saying Kuroka killed somebody to protect her.

Koneko didn't talk about her sister again the rest of the trip.

They reached a lake in the forest.

"Okay Koneko, strip naked and follow me... you can leave your bra and panties on though. You're going to be getting wet, so lets keep your clothes dry." Naruto stated, and he didn't give Koneko any privacy. He didn't make it a point to watch as she turned a little red in the face, and though she gave him a slight glare, she still reluctantly stripped her clothes.

Naruto glanced at her.

Himawari had bigger breasts than Koneko had, nothing of importance, it was the Hyuga and Uzumaki in the girl. His mother had been a beautiful woman, who had a slightly above average chest, and his wife had been the only woman in the Hidden Leaf who could compete with Tsunade Senju in chest size.

"Perv."

"Just thinking about how my daughter needs new underwear, and she's a bit bigger than you. Your underwear is very cute. I'm hopeless at underwear shopping, so I would appreciate if Himawari could have somebody to get her a couple new sets." Naruto had no ulterior motives under than looking at her underwear, as a father would when thinking about what his daughter needed. "You've got a very toned body, you should feel very proud that you trained so hard that your muscles are all lean. Most women would kill to have your slim figure." Naruto complimented the girl.

Koneko smiled, she glared at him, but she still smiled a little at the compliment when Naruto turned away from her and walked onto the water.

She blushed when she saw Naruto take his jacket off, and reveal a white shirt he wore underneath it. He tossed his jacket onto the grass, before she noticed that he was walking on the water like it was solid ground.

"... How are you doing that?" Koneko asked him with a furrowed brow.

"You can use Senjutsu, but you haven't mastered your chakra. Usually, I would have you start off walking up trees. Start using Senjutsu, and spar with me on top of the water. Of course, if you fall into the water you're going to get burned." Naruto explained to her as his body started to steam. Naruto took his sandles off, and tossed them onto the ground. His feet made direct contact with the water.

It bubbled.

Koneko gulped when she saw the water bubbling violently, showing that the water around Naruto had reached the boiling point. It was good that she had taken her clothes off, or falling in the water would have gotten her clothes soaked in boiling water.

"... How long are we going to be working on this today?" Koneko asked him.

"As long as it takes."

...

"Huh?"

"This training won't end for the day until you master how to walk on water. If you run out of chakra, I'll use my chakra to refill your reserves. If you get injured, I'll heal any injury you get that would stop you from training. I'm going to beat the crap out of you until this lesson sinks into your skull, and maybe you'll pick of some taijutsu training while we're at it." Naruto told her as he raised his fists up.

He was going to be merciless.

"... What about food or water?"

"This is a fresh water lake, you'll have plenty to drink when you're underwear. Of course, you'll have to drink boiling water, but it will keep you alive. There won't be any breaks, any rest, or stopping until this lesson is learned. After this, we'll be teaching you an easier lesson, that will be your rest, then we're going to the harshest training." Naruto gave her their training regime for the next 20 days.

Naruto vanished.

Koneko was punched in the face and sent flying onto the water, skipping over the water a couple of times with her body. She sank underneath the water, and got a mouthful of water that she swallowed. Naruto grabbed her by the wrist and yanked her out of the water, before he kicked her in the gut.

"Gah!?"

Koneko's blood stained some of the water red when it came out of her mouth, and she landed on her feet on the water for a brief moment. Her cat ears and her tail were both out, Naruto had beat the literal transformation out of her body. Unable to hold her human transformation, she could sense what Naruto was going with his chakra better. She sensed an unsteady stream of chakra coming out of his feet.

She sensed what he was doing, but she didn't replicate it correctly, and started to fall beneath the water.

Or not.

Naruto gave her an uppercut to the jaw, and sent her flying through the air, or she would have gone flying if he hadn't twisted and kicked her in the chest. His assault was relentless, just as unending as he pretty much said it was going to be.

"I gave your mother what she needed to do, and let her figure it out herself. I was the Master that she needed me to be for her. I was kind and understanding with Kuroka, and helped her deal with her issues. I was the Master she needed... I'm going to beat the ever loving fuck out of you, because that is the kind of Master you need." Naruto told her as she landed on her feet, and she stayed on the water, for less than a second before she fell underneath into the boiling water below.

She gave a quick scream of shock and pain, and Naruto reached under the water and yanked her out of it again. Not without quickly elbowing her in the nose, and grabbing her by the neck as he jumped off of the water and channeled his chakra through her.

He slammed her into the surface of the water.

"AH!"

It was like her back slammed into concrete, Naruto had used her body as a medium to send his chakra into. He used his chakra to allow her body to stand on water, but sadly, since he was slamming her into water it still hurt a lot. Naruto stopped channeling his chakra, and allowed her to sink beneath the water again.

She quickly summoned her wings and tried to fly out.

She came out of the water, but Naruto kicked her in the face.

"No flying, use only Senjutsu and chakra to train. Put your wings away Koneko, or I'll drown you." Naruto shoved her head underneath the water. He held her face beneath the surface, and she struggled as much as she could.

Her wings retracted into her body, and Naruto allowed her to breath.

"You... sadistic fuck."

"It's called training, I'm going to break and heal every bone in your body until you learn the lessons you need." Naruto gave lifted her out of the water completely.

The brutal beating continued.

-2 days later-

The brutal beating continued for another 2 days.

Naruto kept true to his promise, and he had not allowed her to eat a meal since their training started. She was tired and hungry, and despite the fact that Naruto kept healing her injuries when they got to be too much for her, currently her left arm was broken, and several... most of her ribs were in a similar situation. Her skull had been fractured slightly, and what part of her body that wasn't covered in her own blood was covered in bruised. Her right eye was swollen shut, her nose was broken and bleeding, pointing to the left. Her face in general was swollen to the point it was hard to recognize her.

Whenever she ran out of chakra, Naruto didn't even allow that to keep her from training, and he just gave her more chakra to train with. He converted his chakra into her chakra, and transfered it to her... using his fist to punch her. She learned that as long as he touched her, he could give her chakra.

He healed her injuries with his fists.
He restored her chakra with his fists.

Koneko was standing up, beaten to the point you couldn't even tell who she was at the moment. Yet, since Naruto hadn't healed her yet, that meant that she was still able to keep fighting. She was running on pure adrenaline, since her body was being put into a constant state of near-death and her life was being threatened the entire time that she was training. She needed sleep, and was barely awake at the moment.

Naruto was very good at beating her to the point she could see death's door, but never cross the line into actually killing her.

Naruto snapped his fingers.

Koneko's body was enveloped in a shroud of pure chakra, and she felt her bones snap into place and quickly heal. Her sleep and food deprived brain wasn't registering what was happening at first, since she wasn't getting punched yet she was being healed. She felt her chakra reserves being restored by Naruto's chakra once more, and she looked towards Naruto standing on the water, and he was looking down at her with a wide smile.

"Congrats Koneko! You've now Mastered how to water walk, it only took 2 days to master it. Look down at your feet!" Naruto exclaimed to her while clapping his hands.

She looked down.

Her eyes were blurry, but even with blurry eyes she could see that she was standing on the water. She blinked a few times, before she noticed that her chakra reserves were slightly larger from the point that they started. They weren't a huge amount larger than when they started training, but over the course of 2 days of constant training, she would guess that her chakra reserves were maybe... 6 or 7% larger than they had been before.

Her chakra wasn't just larger, but it had become slightly more refined as well.

"Uuuuuh."

"Good work, next we're going to spar... Earth Style: Mud Wall!" Naruto clapped his hands together, and a massive wall of rock came out of the forest next to them. It shot up into the air, and several trees had been caught by it and were coming out of the side of the wall. "We're going to be sparring there. Once you've gotten a meal and 8 hours of sleep, we'll begin the next bit of your training... this training will be easier. You've just got to walk up the side of that 2,000 foot wall using only your chakra while sparring with me." Naruto exclaimed how simple and easy her training was going to be.

Koneko passed out.

18 days of training remaining.

18 more days of hell to go.
